Anti-theft label and its assembly method

ABSTRACT

This invention provides an improved anti-theft label and its assembly method. It uses paper box and paper sealing gasket to replace PVC box and PET sealing gasket. The anti-theft label applying the technical scheme of this invention is nontoxic and does no harm to human health. It can be used safely, and is the new generation of anti-theft label that is good for environment protection and represents the main developing trend of future anti-theft labels. Moreover, in the improved anti-theft label in this invention, we use double-sided gummed paper that can easily get from market to replace self-adhesive glues which needs to be sprayed. The assembling techniques are simpler; consequently the production efficiency can be significantly improved.

BACKGROUND OF THE INVENTION

This invention refers to an anti-theft label and its assembly method.

Presently, in libraries, bookstores or supermarkets, magnetic anti-theftlabels are commonly used on books or other commodities in order toprevent them from being stolen. Generally speaking, anti-theft labelsare fixed on books or other commodities by means of “sticking”.

The existing anti-theft labels, whose configuration as shown on PIC-1and PIC-2, are composed by PVC vented box 1′, where polarizer 2′ andpolarizer 3′ are placed inside. The opening part of the PVC vented box1′ is covered with PET sealing gasket 4′. PET sealing gasket 5′ ispressed on the upper part of PET sealing gasket 4′, while magnetic bias6′ is set between sealing gasket 4′ and sealing gasket 5′, whoseposition corresponds with that of polarizer 2′ and polarizer 3′. Thesurface of sealing gasket 5′ is coated with self-adhesive gules 7′, andon the self-adhesive gules release paper 8′ is overcastted. Whileassembling, firstly, place polarizer 2′ and polarizer 3′ inside the PVCvented box 1′, press magnetic bias 6′ in between PET sealing gasket 4′and sealing gasket 5′, then bring PET sealing gasket 4′ and sealinggasket 5′ together by Heat Press and fix magnetic bias 6′, enabling itcorrespond to polarizer 2′ and polarizer 3′. Afterwards, place PETsealing gasket 4′ at the opening part of PVC vented box 1′ by HeatPress, then spray self-adhesive glues 7′ on the surface of PET sealinggasket 5′, and finish assembling by covering release paper 8′ onself-adhesive glues 7′. This type of anti-theft label and its assemblymethod has the following disadvantages: {circle around (1)} the ventedbox uses PVC materials, which is one of plastic products that causesevere pollution to environment and damage to human health. Moreover,PVC is non-recyclable material, once burnt, will produce dioxin andfuran, which have very strong toxicity and Carcinogenicity. Nowadays PVCas a raw material is prohibited in many fields. {circle around (2)} thetechniques of spraying self-adhesive glues on PET sealing gaskets arevery complicated, resulting in low efficiency.

BRIEF SUMMARY OF THE INVENTION

The aim of this invention is to provide a green simply improvedanti-theft label and its assembly method.

The technical scheme of this invention goes as follow, improvedanti-theft label, including polarizer and magnetic bias. Above-mentionedpolarizer is placed inside a paper box, whose opening part is coveredwith paper sealing gasket. The lower side of above-mentioned magneticbias is adhered to the upper side of above-mentioned paper sealinggasket, corresponding to the position of above-mentioned polarizer. Theupper side of above-mentioned paper sealing gasket is covered withdouble-sided gummed paper.

Above-mentioned paper box is made from paper pulp.

Above-mentioned paper box is made of cardboards.

Above-mentioned sealing gasket is made of laminated paper.

The assembly method of improved anti-theft label can be realized withthe following steps:

-   -   Step1: preparing paper box;    -   Step2: place polarizer into above-mentioned paper box;    -   Step3: stick paper sealing gasket at the opening part of        above-mentioned paper box;    -   Step4: stick magnetic bias to the upper side of above-mentioned        paper sealing gasket, corresponding to the position of        above-mentioned polarizer.    -   Step5: cast double-sided gummed paper on the upper side of        above-mentioned paper sealing gasket, so as to fix the magnetic        bias in between above-mentioned paper sealing gasket and        double-sided gummed paper. And an improved anti-theft label is        done.

The paper box used in step1 is paper-pulp box made by paper pulpprocessing techniques that are commonly used.

The paper box used in step1 is cardboard box composed by cardboards withthrough holes and bottom sealing cardboard stuck to the lower side ofthe through holes.

The paper sealing gasket used in step3 is laminated paper.

-   -   The thickness of above-mentioned cardboards is 0.5 mm-1.5 mm.

The thickness of above-mentioned bottom sealing cardboard is about 0.2mm-0.4 mm.

With the adoption of above-mention technical scheme, PVC vented box andPET sealing gasket are replaced by paper vented box and paper sealinggasket. The improved anti-theft label in this invention is nontoxic anddoes no harm to human health. Being able to be used safely, it is thenew generation of anti-theft label which is good for environmentprotection. Nevertheless, it is easier to print designs on paper box,which is the main developing trend of future anti-theft labels.Moreover, in the improved anti-theft label in this invention, we usedouble-sided gummed paper that can easily get from market to replaceself-adhesive glues which needs to be sprayed. The assembling techniquesare simpler; consequently the production efficiency can be significantlyimproved.

DETAILED DESCRIPTION OF THE INVENTION

The improved anti-theft label in this invention, as shown on PIC-3 andPIC-4, includes paper pulp box 1, two pieces of polarizer 2, laminatedpaper 3, magnetic bias 4 and double-sided gummed paper 5. Two polarizer2 are placed inside paper pulp box 1, laminated paper 3 is stuck to theopening part of paper pulp box and seal it, the lower side of magneticbias 4 is fixed to the upper side of laminated paper 3 and correspondsto the position of polarizer 2, double-sided gummed paper is covered onthe upper side of laminated paper 3, pressing magnetic bias 4 in betweenlaminated paper 3 and double-sided gummed paper 5.

In this invention, laminated paper 3 can be replaced by ordinary paper.Seal the opening part of paper pulp box 1 with ordinary paper by usinggumwater or other binding agents.

In this invention, the paper box 1 is made by commonly-used paper pulpprocessing techniques. Paper pulp box 1 can be replaced by cardboardbox, which can be made by 1 mm cardboards with through holes and 0.3 mmbottom sealing cardboard stuck to the lower side of the through holes ofthe 1 mm cardboards. The assembling method of improved anti-theft labelcan be realized with the following steps:

-   -   Step1: preparing paper box; it can be paper-pulp box made by        commonly-used paper pulp processing techniques or cardboard box        made by 1 mm cardboards with through holes and 0.3 mm bottom        sealing cardboard stuck to the lower side of the through holes        of the 1 mm cardboards.    -   Step2: place polarizer into paper pulp box/cardboard box;    -   Step3: stick laminated paper at the opening part of paper pulp        box/cardboard box; laminated paper can be replaced by ordinary        paper. Seal the opening part of paper pulp box/cardboard box        with ordinary paper by using gumwater or other binding agents.    -   Step4: spread gumwater or other binding agents on the upper side        of laminated paper at the position corresponding to that of        polarizer, then place magnetic bias on the binding agent to fix        it.    -   Step5: cast double-sided gummed paper on the upper side of        laminated paper, so as to fix the magnetic bias in between        laminated paper and double-sided gummed paper. Thus an improved        anti-theft label in this invention is done.
